Modulating the packing of [Cu-24(isophthalate)(24)] cuboctahedra in a triazole-containing metal-organic polyhedral framework

The highly porous (3,24)-connected framework NOTT-122 incorporates a C-3-symmetric angularly connected isophthalate linker containing 1,2,3-triazole rings and shows body-centered tetragonal packing of [Cu-24(isophthalate)(24)] cuboctahedra. This unique packing, coupled with the high density of free N-donor sites, is responsible for the simultaneous high H-2, CH4 and CO2 adsorption capacities in desolvated NOTT-122a.
